AppIication filed March' 25, 1915. Serial No. 17,034.

To all/whom t may concern:

Be it known that I, HENRY L. Turnier, a citizen of the United States, and a res1- dent of South Dartmouth, inthe county of Bristol and State of Massachusetts, have invented an Improvement in Cone Tubes, of

tion withthe'accompanying drawings, is a specification, like characters on the drawings representing like parts.` `A

This invention relates to cone tubes adapted to receive or have wound thereon yarn,

l y thread or the like of the commonly known u so cone windin form and from which thel yarn is drawn o axially or substantially so.

In certain aspects thereof, my invention is an improvement upon that shown'in the patent to Charles Gess, No. 986,379, dated March 7, 1911.

In order thatthe principle of the invention may be readily understood, I have 4disclosed a single embodiment thereof inthe accompanying drawing, wherein- Figure 1 is a side elevation of a cone tube embodying my invention;

Fig. 2 is a vertical, central section thereof;

Fig. 3 is a plan view of the tube shown in Fig.l; l

, Fig. 4 is across sectional view thereof;

Fig. 5 is a sectional view of thetip end lof the tube; and

Fig. 6 is a plan view o f thel blank from which the cone tube is wound. j 4

Cone tubes adapted to receive or have .yarn or threadA wound thereon and from which said yarn or thread is drawn `oil? ax- 5 ially when in upright position are custome arily formed Aof paper rlled in one or more layers or coils into conical form.

rIhese tubes are adapted to be mounted for winding upon tapering arbors of the general shape of the tubes and extending through said tube to within an inch or' two ofthe f tip end thereof. Theends of these conicalyat tubes generally protrude somewhat from the complete yarn or thread" mass. A cone tube y of this general character but having an inf" q turned a ex end is disclosed -in said Gess" Patent o. 986,379,and I have representedv the disclosed embodiment of my invention as applied thereto.

y Referring more particularly to the draw-l ings and to the single' embodiment `of the invention here' illustrated, the 5 blank -fro1rnl which the cone or tube is formed is represented at 1 in Fig. 6, it'beingpreferably of Specification of Letters Patent.

with each other, as indicated at 2 in Fig. 5..

Owing to the fact that the conical tubes are markedly tapering to facilitate the unwlnding of the yarn or thread (such tapering materially exceeding that of the usual spinning spindle), it is exceedingly important in effecting the best results that such cone tubes be supercially roughened, thus preventing the slipping or displacement of the yarn or thread as the first series of layers thereof are wound upon the ytube and subsequently. This tendency to displacement, particularly of the iirst laid layers, exists to a marked degree in a cone'having a decidedtaper, but it is nevertheless of importance that the cone .tube and the yarn to the coiling of the paper or other material into tube form, but preferably while the material is in its flat form. If as prepared the cone tube be superiicially vroughened, the roughened portionis removed from the tip portion of the tube which, as stated,vshould present noobstruction to theunwinding of the yarn or thread and es ecially to the unwinding of the first laid ayers thereof.

In order to preventthe first laid coils or layers of the yarn orthreadvfrom contacting with `the tip end of the cone tube as they are unwound therefrom,the tip end 5 thereof is inturned or upset in any suitable manner, as represented most clearly in Figs.

v1, 2 and l5.' The' tip end of the cone tube should,A for effecting the best results, be very materially inturned and preferably so as substantially, if not wholly, to closesaid tip end, and the inturned end may be turned into, the-cone tube to any desired extent so 'as to provide adownwardly extending-edge portion@ v 1 The tipend of the cone tube, asyarn or if thread is being wound thereon, rejects very materiallyfbeyond the taper end of the supporting arbor. The approximate position of the outer end of the arbor'is indiire-- tip end of the cone extends beyond ,the

of the cone and is provided with stift', cone j supporting, side walls to sustain the usually large and heavy package. The tip end of the cone preferably is not only inturned but is smooth, the roughened surface of the body of the cone blending into the smooth, inturned surface of the tip. The said inturned tip end is preferably indifferently centered internally -with respect to the axis of the cone, this being possible because the driver. This is a matter of practical importance, inasmuch as if, in manufacturing the cone, the apex end thereof be somewhat v warped or distorted, the fact that the tip end extends beyond the driver permits it to conform in position substantially to the driver, whereby the yarn or thread as drawn o will not be obstructed or impaired by said warped or defie'cted portion.

In accordance with my invention, I suitably reinforce the tip portion of the tube and this I preferably effect by treating it eol with some suitable material, such, for example, as sizing, as indicated by the heavier section lines 6 in Fig. 2. Inasmuch as the tip portions of the cone tubes protrude some.- what from the formed packages, such tip ends are liable to becom'e crushed or some what damaged during transportation. An important object of my invention is to overcome this defect which preferably I accomplish by treating the tip end. So far as I am aware, I am the first to treat the tip end of a cone tube for this purpose, and I shall therefore claim the same broadly whether the tip end be inturned or not, but in its preferred embodiment I contemplate the inturning of the tip end of the cone tube, such inturned tip end being sized or otherwise suitably treated at any suitable time, but for reasons hereinafter' set forth being preferably treated subsequent to the inturning. Such treated tip end of the cone tube is ,preferably subsequently polished, so that said cone tube in its preferred embodiment has an intuined, treated, polished end which not only presents no obstruction to lthe unwinding of the layers of yarn or thread, but cannot readily becrushed or damaged in transportation. The sizing or treatment of the tip end may extend downward to any suitable point.

The inturning of the tip end of the tube may be eected in any suitable manner or by any suitable means not herein necessary particularly to disclose. In effecting the 1n` turning of the tip end of the tube, the material of such tip may be somewhat twisted orcircumferentially displaced, as indicated at 7 in Figs. 1 and 3.

When the cone tube is in its normal condition,that is, before the tip end thereof has been inturnecL-such tip end is substantially unyielding to inward pressure. When, however, the material of the tube has been circumferentially displaced, then the arch eect existing prior to inturning is materially lost and the twisted portions of the edge, because of their displacement, will more readily yield inwardly. This inturning may be satisfactorily effected by subjecting the unturned end to the action of avdie, the die and cone tube having a movement of relative rotation. Such relative rotation of the cone tube and die coincidently softens the matelrial of the tip end portion, thus enabling it to be turned inwardly and to lay snugly in the die and to receive the smooth, highly de-v sirable, polished surface. Such softening of the tip end renders such tip end less stifi:l and lacking in rigidity than the body yof the tube, it being therefore more pliable and yielding than the body thereofl This, however, renders the tip end liable to be crushed or damaged in transportation and to overcome this I treat the tip end as heretofore set forth and preferably by subjecting it to the action of some suitable material, such, for-example, as. sizing, by means of which such softening or yielding character is offset or neutralized. In adapting my invention therefore to a cone tube having an inturned end, I preferably apply the stifening material thereto after the inturning thereof has been effected, lthus neutralizing, partially or wholly, the softening action incident to the inturning of such tip end.

The sizing or othermaterial i's preferably so applied to the inturned end and subsequent to the inturning action that it neutralizes the softening of the end created by or incident lto the inturning action, and therefore the finished cone tube with its inturned treated end is of substantially uniform stiffness throughout. This result has never heretofore been accomplished so farv as I'am aware. The sizing or other material 4may be applied in such excess as to result in making the tip end of the cone tube stronger than the 4body thereof.

I have found in practice'that if the inturned end be supericially polished and smooth, it will not offer such resistance to the yarn or thread as to chafe or break the latter, even though such inturned end be reinforced or stiffened by subjecting it to the .action of sizing or other suitable material.

The cone tube is preferably formed from tation, the scope of the invention being set forth in the following claims.
